So when it says the are looking for an aftermarket supplier that means Keihin is looking for someone else to make the carbs or they are looking for another Sudco type company?
Keihin is looking for a company to be a distributor for the USA like Sudco. I have been doing business with Sudco since around 1975. It is a shame that the markets have changed and the business has been on a gradual decline the last 20 years or so, when the son of the originator of Sudco started running the business.
Keihin makes carbs and tuning parts for the OEMs. Keihin also make generic carbs and tuning parts for the aftermarket. OEM carbs and tuning parts have to be purchased from a Honda, Yamaha, Suzuki.....etc.... dealer. Sudco sells aftermarket carbs which often share the same raw carb castings, but the fuel and air circuits are often drilled different sizes and sometime are not in the same locations. Keihin will not sell OEM needles, needle jets, and other parts that were engineered and tested by the motorcycle manufacturers for a specific year, make, and model.
